FAQ

Is this a legally-binding e-signature?
No — this draws your signature as an image onto the page. There is no certificate, identity verification or audit trail, which a legally-binding e-signature service would provide. Use this for informal signing (initialing a draft, personal forms), not contracts requiring verified e-signatures.
Can I resize my signature once placed?
Not yet — it places at a fixed size; remove and re-place it if the size is wrong.
Does this tool upload my PDF or signature anywhere?
No — the signature is drawn, placed and exported entirely in your browser.
